"Peter Hotez, professor of tropical medicine at US-based Baylor College of Medicine and a co-editor–in-chief of PLOS Neglected Tropical Diseases, says that integrated NTD control through mass drug administration (MDA) is now under way in about 20 African countries.

He adds that in some cases such activities are leading to the elimination of lymphatic filariasis, onchocerciasis and trachoma, while for other NTDs the prevalence is being gradually reduced."
